An introductory route in Le Grand Souterrain at Girolles, from a narrow crawlway to a spacious chamber via a ten-metre shaft.
Descrizione
Morfologia
One enters the cavity through the upper access: it is narrow, but the gallery quickly takes on more agreeable proportions. It ends at the top of a small vertical drop. Behind, a crawlway leads to the top of the ten-metre shaft. Narrow at its top, it widens out to open into a chamber, the most spacious part of the cavity.
Progressione
Here is the route we will retain, in the context of an initiation or a first discovery. The small vertical drop is negotiated by stemming (installation of a handline recommended on the left wall). A fifty-metre crawl allows one to regain the open air by exiting through the lower access of the cavity.
